Abstract

Shallot production is affected by the cultivation techniques, one of them is seed coating. The technique is a practice by covering seeds by using particular substances such as growth regulators, micronutrients, fungicides, or antioxidants that increase seed vigor in the field. Micro nutrients and growth regulators can be collected from rot fungi. This study aimed to determine the leaf chlorophyll content and root diameter of shallot plants with seed coating used 4 superior rot fungi isolates that applied using single and combination isolates. The research was arranged in an experiment using a Randomized Block Design consisting of 11 treatments repeated 3 times so that there were 99 experimental units. Leaf chlorophyll content was measured by SPAD-502 plus chlorophyll meter, while the length and width of the leaf was measured by Leaf Area Meter. The results showed that seed coating with combination of Tramella sp + Pleurotus sp isolates gave the best response to the leaf chlorophyll content and the primary root diameter of the shallot. The highest content of leaf chlorophyll was 0.029 nm with a primary root diameter of 1.33 nm. Seed coating with a combination of rot fungi isolates is likely one of the techniques to increasing plant growth and chlorophylls content.
